Most electrical components also use a relay so check for one, then check the headlight switch itself. The switch will tell the motors to activate via the relay.
Bad starter solenoid? Loose or corroded battery terminals? Weak battery? Bad neutral switch?
Can be a dead battery, defective starter, loose or corroded battery connection, or blown main fuse. If nothing comes on when you turn on the ignition switch and your interior lights are not working it is not the starter.
Make sure that car has gas in it. Then check if the starter.
I had a similar problem turns out the Alternator was bad.
The starter solenoid near the battery should be checked.
Pop the hood there is a bulb behind the headlight you need to twist it out counter clock wise and pull out, on my subaru i have to pull out battery to get to driver headlight, other then that if nothing is on the way is just get hold of it untwist and when putting new one in make sure not to touch the glass part of the bulb reduces the lifetime of the bulb.
Check all the fuses, check fusible links, exc.
Unhook your negative battery cable for a couple hoursand hook it back up. Works for me, sometimes.
I would check the weiring harness from the car to the starter
It has a dead cell. I know it is only 2 years old but it happens especially if that battery was run completely down which shortens the life. I suggest you purchase a different brand as this brand was not very dependable. My answer is assuming nothing is on pulling power from the battery when the car is just sitting. Have the battery checked to make sure it is actually defective. Any auto parts store will check it for you. It has to be fully charged in order for it to be checked.
Sounds like you have a bad ground issue with this vehicle,possibly a bad headlight switch.Checking for either will take experience and a wiring schematic.Good luck! ** Also check you battery. Sometimes turning on lights will strain a weak battery.
If you need a battery then there is nothing that can replace it.
